Ensuring an exit strategy: RTEL1 restricts rogue recombination.
Success of homologous recombination-based DNA repair depends not only on recombinases, which promote invasion of the homologous DNA duplex that serves as a template for repair, but also on antirecombinases, which dismantle recombination intermediates to allow completion of repair. In this issue, Barber et al. (2008) identify a previously elusive antirecombinase activity important for maintaining genome stability in animals.
